So my husband repaired twice now our master bath tile area due to wet area behind the tiles that are now greyish again. Where the tiles meets the tub the grout seems to be obsorbing water and it gets up to one tile up. If I were to remove the grout and allow the area to dry what kind of materials in terms of seals, grout would I need to avoid this from happening again. I once told my husband to take out the colored grout and just use a caulking would that work? If no, please help.

There is probably sheet rock behind that tile that's already ruined... the only way to really fix it if that's the case is to rip out the damaged and wet material, and redo the job from scratch.

Grout is for between thet iles, not where the tiles meet the tub. That should be a bathroom caulk like http://www.google.com/#hl=en&gs_nf=1...w=1675&bih=824

Damage is done and repair may require removing tiles and whatever board is back there. You can not use drywall, you neeed cement board. They used drywall many years ago, switched to greenboard and they all fail in wet areas.

I actually prefer Cement or backer board... green-board is water resistant.. not water proof... but agree it is still far better then regular sheet-rock. Price is only marginally higher. But then I tend to overcompensate on the side of caution.
